To all whom t may concern.'

Be it known .that I, EDUARD von HLsnN, of Charlottenburg, Germany, have invented certain neuT andusefulImprovements in Stenographic TypeNVriting Machines, of which the following is a specification.

This invention relates totype-Writin g machines; andthe prime Objectis to provide means whereby upon depression or `manipuf lation of a plurality of keys simultaneously the corresponding type will be successively struck, thus enabling s hort Words and syllaf bles to be Written at a single stroke by the operator, which obviously permits increased speed. The arrangement for accomplishing this end may be broadly stated to be a typeselecting mechanism comprising means set in motion to complete a cycle of movement by the manipulation of a plurality of keys simultaneously or by the' manipulation of a' single key, such means being common to all the keys, and by this is meant that such means by such manipulation receives an impulse to carry it through a movement embracing all the type in the sense that in the course of and by reason of such movement any type may become operative to print. The selecting mechanism also includes devices, controlled by the keys, Which by cooperation with the aforesaid key-impelled means effect a selection of typefcorresponding AWith the keys strucki Thus the number of type se1 lected for printing by a single stroke of the hand or hands of the operator is only depend-` ent on the number of keys simultaneously manipulated, for in every instance the key-I operated means is impelled to complete a cycle of movement which embraces all the keys. The type-selectin gis accompanied by a printing operation, Which is dependent upon cooperation of the above-mentioned elements of the type-selecting mechanism.

In one mode of carrying' out the abovestated idea I arrange the type on a carrier, (which may be a Wheel or other movable support,) so that in a single rotation of the type- Wheel or corresponding movement of a di'i't'erent form of carrier the type will be brought successively to printing position. By reason of manipulation of one or any number of keys ot' the machine suchrevolution or corresponding complete movement of the t`ypecarrier would ensue inthe absence of any obstruction; but a yielding form of connection between thety'pe-carrier and the keys is provided toabsorb the movement incident to manipulation of a key or keys when the type-Wheel is obstructed. By such an arrangement it Will be seen that when a key or keys are manipulated, if therotation of the gtype-.Wheel does.` not. immediately ensue, a power is in any event storedwhereby such l rotation Will eventually. be completed Without furthermanipulation of the keys.'A Thus by arranging suitable locking or stop devices Whose operativeness is controlled by the keys the type-Wheel can be checked in its rotation with any one of its type inposition to print, and still upon its release its movement will continue, and it may beohecked again with another type in position to print, and the complete alphabet might by this method be printed by'but a single stroke, if thereby all the keys were manipulated. Instantly upon the type-Wheel being checked with a type in position to print the. printing-couple, one `of which is, of course, the type-Wheel and the other its opposed impression-bed, will be caused to coact through suitable mechanism dependent for its freedom to operate upon the actuation of means rendered operative by manipulation of the keys and operating to actuate the type-Wheel-locking devices'. A quick `recovery or retraction of the said locking means takes place, While the separation of the printing-couple is as quickly brought about, so that the type-Wheel may proceed and be locked in another position. and the printing-couple agaiu'caused to coact Incidentally the feed movement of the paper-carriage takes place,

'this occurring fsimultaneously With the sep* aration of the printing-couple and `preferably caused by the means employed to eltect such separation.

The invention, as indicated above, may be embodied in a great variety of Ways, all of which I'shall not here attempt to illustrate or describe, confining myself to an explaination in detail of one complete form of embodiment ot the invention and several modifications of parts thereof and then appending claims reciting essentials ofthe invention ,Without limitation to any one specific form of embodiment u thereof.

TOO

I preferably arrange for the printing movements or coaction of the printing-couple to be effected by the momentary release of a stored power, which may be a spring-motor normally held in check through restraint of its escapement lever or pallet by a detent arranged to be displaced by the normally inoperative means hereinbefore referred to as actuating the type-wheel-lockin g device, the said means being set for operation by the manipulation of the keys. It is to be understood that such detent-displacing and type-wheel-lock-operating mechanism does not act immediately upon manipulation of the keys, but is thereby simply put in readiness to be operated whenever a type corresponding with a struck key comes to position to print. Operation of this previously-prepared mechanism is effected by the rotation of the type-wheel,which has associated with it a series of abutments relatively arranged to correspond with the location of the type, so that upon a type corresponding with a struck key coming to position to print the corresponding abutment, moving with the type-wheel, may operate the detent-displacing mechanism set by manipulation of that key, which mechanism also operates the typewheel-locking device.

The drawings which accompany and form part of this specification illustrate embodiments of the invention.

I have here shown the invention embodied in a machine of the type-wheel variety, and the type will be arranged in two lines on the periphery of the wheel in such order as to have those consonants which occur most frequently at the beginning of words or syllables precede the vowels, and then followsa repetition of consonants which occur most frequently at the ends of words and the letter e This can best be demonstrated by giving the lines of type, thusbdksmvfgpnctwhjlrqvxyzeoaiuflnstre,.:-; BDKSMFGPNCTVIIJLRQVXYZEOAIU2"34567S9?i It is to be understood that the lines of type as above given are to be placed on the periphery of the type-wheel so that when the latter stands in its normal position the first letters of the lines-viz., b and B -will be positioned in juxtarelation to the impressionbed, and the type-wheel turns in a direction to bring the other type in the lines successively to such position. Hence in a complete revolution of the type-wheel many combinations of type to make up words, syllables, and diphthongs can be obtained by reason of the arrangement of the type above explained.

The arrangement of the keyboard is such that the left hand of the operator can most conveniently be employed to strike the consonants and combination of consonants occurring most frequently at the commencement of Words, the thumb of the right hand to strike the vowels, and the fingers of the right hand to strike the consonants and combination of consonants occurring mos-t frequently at the ends of words. The keys are so arranged as to permit the striking of the combination of letters which most frequently occur with the least possible changing of the positions of the hands and fingers from what may be termed the normal position. This :normal position as the keys are arranged in Fig. II is as follows: The little finger of the left hand over s, theindeX-nger over t, the thumb over w, and the other two fingers over g and h,7 the thumb of the right hand over a or u, the index-finger over 11, the little finger over 1, and the two other fingers over r7 and t The general working of the machine consists in this, that upon depression of one or several of the keys motion is imparted to the typewheel to carry it through one complete rotation; but whenever a type corresponding with a depressed key' comes to position to print the rotation of the wheel is checked and it is caused to move against the impression-bed to printand then back again to normal position, while the paper is fed and the wheel released for further rotary movement. Thus any word or syllable where letters occur'successively in the type-linecan be printed by one stroke of the hand, the fingers being placed on theproper keys.

Passing on now to a detailed description of the form of mechanism shown in Figs. I to IX, inclusive, the numeral 2G designates a ICO IIO

, bearings on a suitable base, said slide carrying a cylinder 19, around which the paperis to lie and which constitutes an impressionbed for the paper. The said carriage also carries a rack 27, which will be referred to hereinafter. The numeral -1 designates theV type-wheel, which is arranged `over the cylinder 19, with its axis at right angles thereto, and is designed to move toward and-from the said cylinder, being for this purpose mounted on a swinging journal 11, so as to rotate therewith, but capable of longitudinal movement thereon to bring the line of capital type to printing-plane. (The means for shifting the type-wheel on its journal are not here shown, as they form no part of the. present invention.)

Movement of the Swingin g journal with the type-wheel toward the cylinder is effected through connections with a spring-motor of the following-described form and construction, reference being had more particularly to Figs. I and III: A shaft 30 is journaled in a suitable framework adjacent to the papercarriage and partially overhanging the same, and a toothed wheel 28, loosely mounted on vsaid shaft, engages the rack 27, so that upon `the reverse traverse of the carriage said wheel will be rotated thereby. This wheel carries a pawl 29, which engages a ratchet-wheel 30, fast on the shaft 30,to which is also affixed one end of a helical spring in-closedwithin a box 3l, the outer end of the spring beingfas'tened to the box. A gear-wheel 32 is fastened to the said box and meshes with a pinion 33.011 a shaft which also carries an escapementwheel 33 and a cam-wheel 39 in the form of a ratchet-wheel. It will now be seen that upon the paper-carriage being run back for .the commencement of a line of printing the spring-motor above described will be Wound up, the rack 27 turning the gear 28, and that in turn rotating the spring-shaft 30 through the medium of the pawl 29 andratchet-wheel 30. The latter is prevented from turning backward by a pawl 3S, pivoted to a suitable part of the framework.

The spring-motor is normally restrained by the engagement of the escapement lever or pallet 34 with the teeth of the escapementwheel 33a, said lever having anupstanding arm 35, which is held by engagement'with an angle-lever 3G 37, hereinafter referred to in connection with the key-controlled detent mechanism to regulate the operation of the` motor.

Returning now to the means for imparting printing movements to the type-wheel, the

periphery of the cam-wheel 39 engages thc` 10, which at its outer end embraces the' type-V wheel journal 1l. Now it will be seen that when (the cam-wheel 39 is turned `from the position shown in Fig. III the incline of its tooth, acting against the lower end of the rod Aor bar 41, elevates the same, and thereby through the medium of the arm 43 rocks the sleeve 40n and depresses the arm 10 andthe type-wheel. The cam-wheel only turns one tooth at a time, and when the tooth has passed the rod 41 the parts are restored to their normal positions by a suitably-arranged spring 41, the type-wheel of course leavingthe imprint on the paper. It may be well to describe at this point the means employed to advance the carriage, for they operate in conjunction with the mechanism just described for operating the type-Wheel. rlhe elongated sleeve or rock-shaft 40"L above mentioned has formed with it or affixed to it an arm 45, to the outer end of which is jointed a depending arm 44, whose lower end' is formed as a dog or pawl 46 to engage the .teeth of a ratchet-Wheel 47, affixed to the toothed wheel 2S. In the normal condition of parts, or that -shown in Fig. III, the arm 44 stands off, so as to hold the pawl 4G clear of the ratchet-wheel `47 and permit the winding of the spring-motor. When, however, the type-wheel is moved to print 'in the manner above described the -said arm 44 lo'wersand a spring 50, bearing against its back edge, presses it into engagement with the ratchet-wheel47, s0 that upon said arm being drawn up the ratchet-wheel will be turned and the carriage moved one ste'p. The pawl 46 is thrown out of engagement with the ratchet-wheel by thercoaction of an incline 4S in the arm 44 withan abutment 49, suitably arranged for the purpose.

Passing on now to the means for turning the type-wheel so as to bring Hany type desired to `printing position, it is irst to be stated, with reference moreparticularly to Fig, I, that the keys are mounted on vertically-sliding bars 2, which are confined in guides 2 and upheld by springs 6, andsaid j bars bear upon hinged frames 3, which are likewise upheld by springs 5 and are connected by equalizing-links 4. Each frame is composed of a long bar, upon which the keybars 2 rest, and two shortend bars 3, pivoted, as shown at. 3l', to brackets 3, fastened to the frame of the machine. Each key-bar rests upon the long bars of two frames orof one set of frames.` There are two sets of these frames, and they are arranged at an angle to each other, and to the two innermost frames there is attached a chain 7, having two branches for connections separately with the frames and having its upper end fastened to a drum 52. (See Figs. V and VI.) This drum is affixed on a shaft 52L and carries a pawl 53, which engages a ratchet-Wheel54, loose on said shaft and iixedly associated with a gear-wheel 55, also loose on `the shaft `and which meshes with a smaller gear 56, the arrangement being such that depression ofV .any

IOO

one or more of the keys effects a single revochine and rotatively connected with the typewheel journal 11 through auniversal joint 9,'

so as to permit the swinging of said journal in the printing .movements of the type-wheel.

In order to insure the turning of the type- Wheel through a single revolution and no more, the shaft S is provided with a pin G1, which normally occupies a recess or notch in one arm 60 of a bell-crank lever, the other arm 59 of which carries a triangular pivoted abutment-piece G3, against one edge of which a pin 5S on the shaft 52a strikes when 'said shaft is rotated. Rotation of the said shaft therefore disengages the horizontal arm G0 from the pin 61 by tilting the same upward, as indicated in Fig. VII; but immediately thereafter said horizontal arm returns to its original position ready'to drop over the pin G1 as soon as it comes around again,the edge of said rarm being beveled to permit the pin to pass under it. The spring 57 permits the independent preliminary turning of the shaft 52.

A spiral spring G2, connected at one end with an arm on the drum 52 and at the other end with a fixed part of the frame of the machine, exerts itself to hold the pulley in the normal position shown in Figs. V and VI, and so as soon as the key is released this spring turns the drum back to its original position, the pawl 53 sliding over the teeth of the ratchet-wheel 54 and the projection 5Stripping the triangular piece (53 by engagement with its inclined edge and passing by it to take up its original position.

The following-described.mechanism is employed to establish the printing positions of the cylinder according to the key struck by checking and holding the cylinder at proper points. The key-bars all converge toward a central line extending from front to rear, as exhibited in Fig. II, and terminate below a series of hinged plates or flat arms 15, placed vtogether side by side and individually upheld by rods 13, attached at their lower ends to the key-bars and guided at their upper ends in holes in a bar 12, which also constitutes a stop to limit the downward movement of the plates or arms 15. Each of the latter has fastened to its free end a fiat spring 1G, (see Fig. IX,) carrying at its lower end a small abut- -ment 17 with a beveled front and rear face or edge. A guard-plate 2O extends across in front of the series of plates 15, and when the latter are raised, as shown in Fig. IX, the engagement of the lower ends of front inclined faces of the abutment 17 puts the fiat springs 1G under tension. The shaft S carries a number of projections 18, corresponding with the plates 15 and abutments 17 and variously located/around the shaft to correspond with the location of the type on the type-wheel. When any key is depressed, the lowering of the corresponding rod 13 allows the plate 15 upheld thereby to drop to the position shown in Fig. IX", carrying the abutment 17 belowr the guard 2O and allowing the spring 16 to throw it out into the path of one of the projections 18, so that the latter in rotating will press back the block by engagement with the front beveled face thereof. A rectangular frame 22 is pivotally suspended from brackets on the frame of the machine, the pivots being designated by the numeral 21, and the lower bar of said rectangular frame extends behind the series of abutments 17 and is beveled for engagement with the rear beveled edges thereof, as clearly shown in Figs. IX and IX, so that when any one of the blocks is pressed back the frame is also moved, as shown in Fig. IX". Referring now again to Fig. III, there is fastened to said frame 22 a bent arm or rod 23, which is coupled with a pawl or dog 51, and the latter is designed to engage a toothed wheel 24:, fast on the shaft 8, but stands normally disengaged therefrom. When, however, the frame 22 is pushed back, it acts through the arm 23 to draw said dog 51 into engagement with said toothed wheel, whereby the type-wheel is instantly locked. The type-wheel is thus located in a position where the type corresponding with the key struck is opposite the paper, so that upon the typewheel being moved toward the paper that type is printed. I shall presently describe honT the spring-motor is released simultaneously with the locking of the type-wheel, whereupon said type-wheel is moved toward the paper-bed in the manner heretofore described. As the type-wheel completes its printing movement a tooth of the Wheel 33, acting against an arm 51, formed with the pawl 51,disengages said pawl from the ratchetwheel 24, so that the Itype-wheel may be free to rotate further to bring other type to printing position.

Proceeding now to a description of the detent means heretofore adverted to, whereby the spring-motor is released, reference is to be had more particularly to Figs. III and VIII.`

It willbe remembered that the escapementlever 3Li was described as having an upstanding arm This arm projects behind a catch at the outer end of one arm 36 of a bellcrank lever pivoted to swing in a horizontal plane and having its other arm 37 projecting behind the swinging frame 22 to be acted IOO 'IIO

upon thereby when the latter is pushed back j of the detent-catch and takes up its position again'behind said catch.

in i i a .d i I The carriage 2G is moved aside the breadth of a letter as often as the hook 46, Figs. I and III, moved up and down by the escapement 34 33, engages the ratchet-wheel 47 and turns it the breadth of a tooth. After a line is finished the cylinder 19 is turned the breadth of a line by a lever moved by hand, which engages a ratchet-wheel attached to the end of the cylinder. This lever and ratchet-Wheel are not shown in the figures.

The operation of the machine above described may be stated in a general way as follows: The depression of one or more of the keys is converted into rotative movement of the type-wheel, and the latter is stopped and locked by the encounter of a projection on the type-wheel shaft with devices brought into play by the particular key struck. The operation of these devices also effects a release of the motor, so that the type-wheel is immediately moved to print. The return move# mcntof the typewheel after printing is accompanied by the release of its shaft and the feeding onward of the paper the breadth of one letter, so that another imprint can be taken as soon as another projection on the type-wheel shaft sets the detent mechanism to work. Referring next to the modifications, and first to that illustrated by Figs. X, XI, XI", and XI, the arrangement here shown dispenses with the universal joint between the typewheel and the shaft, and the journal and shaft of the type-Wheel are`all one and designated 8, and this shaft is journaled in a swinging frame G3 03% The hinged plates or arms 15 are the same, but springs 1Git are employed without any small blocks; but upon one of the said plates dropping its spring 1G is carried into the path of the projection 18 on the shaft and is pressed back against the frame 22, whose connection with the detent mechanism is the same as before. In this construction the shaft-locking mechanism connected with the said frame v22 is dispensed with, because the downward movement of the shaft is utilized to carry its toothed wheel 24 into en. gagement with a fixed pin 51h. The downward movement of the shaft (which, by the way, is produced through the same train of mechanism as before) also draws the shaft projection 1S free of the spring 16% In Fig. XII an arrangement is shown wherein the pivoted plate or arm 15 is formed at its free end, on the under side, with a lug 16", having a beveled under edge, and the shaft S has the projection 1Sb beveled correspondingly, so that the action of these bevels against each other causes the depression of the shaft. Instead of the hinged frame 22 this depression of the shaft is utilized, through a lever 37, pivoted at G4, to release the escapernentlever, whose arm 35 engages behind a catch 36 at the end of said lever.

In Figs. XIII and XIV means are shown for employing electricity to effect the desired operation s, th at shown in Fi g.V XIII involving the arrangement of the type-wheel shaft 8d in an electric current, the source of electricity being designated at 65, and the projections on the shaft constituting contacts to engage other contacts 16d for closing the circuit, and thereby energizinga magnet 66, with which suitable detent and locking mechanisms can be associated.- Puslrbuttons 2l are employed as the keys of the type-writer, so that only when a key is depressed will a circuit be closed through the corresponding contacts. The electrical arrangement may be varied, as shown in Fig. XIV, where the shaft carries a single contact-arm, which may successively engage contact-pieces 16c arranged in its path and controlled by push-buttons, as before.

In the electrical arrangement the rotation of the type-wheel may be elfected by the closing of a circuit through suitable means applied to the type-wheel shaft to rotate the same. I have not here shown certain adjuncts, such as paper-feeding means and inking devices,V and any well-known or suitable instrumentalities may be employed for these purposes. i

Of course it will be understood that the invention disclosed is capable of embodiment in other forms than those here shown and described and is not, therefore, limited to this extent.
